However, excessive reinforcements in hybrid composites can lead to cracking, while coarse grains in heterogeneous composites improve plasticity but reduce strength. This study combines hybrid reinforcement with heterogeneous configurations for fine structural design of multimodal grained composites using a zonal ball milling process. The reinforcements were selected and the zonal ball milling process was tuned to create three grain zones: (1) nano grain zones enriched with hard SiCnp from high-energy ball milling, (2) submicron grain zones uniformly dispersed by flexible GNS as a transition, and (3) micro grain zones primarily composed of pure Al. The multimodal grained (SiCnp + GNS)/Al composites were produced with grain zone ratios of 35:35:30 and 40:40:20. Results showed that the size and distribution of nano grain zones significantly influenced the strengthening effect of the heterogeneous composites. Com40-40-20 exhibited strong bonding between grain zones, enhancing strain compatibility. Compared to homogeneous (SiCnp + GNS)/Al, Com40-40-20 demonstrated approximately 122 % improved plasticity and about 12 % increased strength without any loss. This refined grain zone design offers valuable insights for optimizing high-performance heterogeneous Al matrix composites.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"194 ","pages":"Article 108926"},"PeriodicalIF":8.1,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

External tooling was found to create excess pressure in the corner region, leading to laminate thinning in the corner apex, while internal tooling showed reduced pressure due to bridging, resulting in local corner thickening in the final cured shape. The matched tooling showed a reduced corner pressure, indicative of lack of contact due to bulk factor in the flange regions that prevented proper seating the tooling, again leading to a final corner shape that showed relative thickening. Across all cases, shape change occurred due to material movement from higher to lower pressure regions and occurred within the low viscosity, pre-gelation time window which correlated roughly with the first dwell in the cure cycle.

Recent research has focused on biocomposites combining biodegradable bioplastics such as polyhydroxyalkanoates (PHAs) with waste-derived fibres to enhance circularity, reduce costs and improve biodegradation. However, current PHA-based biocomposites lack the performance needed to replace conventional plastics, limiting market adoption. This study presents innovative wood fibre biocomposites based on PHAs like poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB) blends, achieving properties equivalent to polypropylene and polyethene.

Thermal analysis and predictive modelling indicate strong interactions between PHBV, P34HB and wood fibres, with mechanical behaviour varying based on P34HB content. The addition of P34HB enhances ductility and flexibility, increasing tensile strain but reducing modulus and strength, while wood fibres improve modulus but reduce strength and strain. Microcrystalline and blend morphology analyses via scanning near-field optical microscopy highlight sensitivity to P34HB content and blending conditions.
