SEM showed increased surface roughness due to the removal of amorphous compounds from the treated fibre as confirmed by the disappearance of certain peaks in FTIR spectroscopy. Resultantly, ∼52% increase in crystallinity was observed by XRD analysis. TGA results also showed the effectiveness of the treatment as mass loss for treated fibres was ∼15% lesser than the untreated fibres. Moreover, thermogravimetric analysis of composites showed highest mass loss in untreated fibres composites and lowest in neat epoxy. The DSC-DTA curves indicated an early start of initiation temperature in treated fibre composite. Tension tests showed ∼12% and ~16% increase in tensile strength and modulus respectively for treated fibres composite due to increased interfacial strength caused by fibre treatment. Treatment also resulted in decreased impact energy and water absorption level.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"26 1","pages":"114 - 127"},"PeriodicalIF":2.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78867846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with that of pure RPUF, the degradation rate of RPUF/MEL-PA composites decreased at a high temperature, and the char residues increased significantly, indicating that the thermal stability of the composites is improved. The smoke density test and TG-FTIR revealed that MEL-PA can significantly inhibit the release of smoke, flammable gases (e.g. esters and hydrocarbons) and toxic and harmful gases (e.g. isocyanate compounds, aromatic compounds and CO), implying significant enhancement of the fire safety of RPUF/MEL-PA composites. SEM, Raman spectra and FTIR spectroscopy were employed to investigate char residues of the composites. MEL-PA was found to catalyse the RPUF matrix to form compact char residues with a high graphitisation degree, significantly inhibiting heat and mass transmission processes during combustion.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"22 1","pages":"145 - 159"},"PeriodicalIF":2.0,"publicationDate":"2022-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90792313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives were to understand the effect of reactive compatibilisation on morphology, crystallinity, thermal stability and mechanical properties. It was found that compatibiliser helps to refine the morphology. It further helps decrease the interparticle ligament thickness and increase interfacial area per unit volume of the dispersed phase (ABS) in the PA6 matrix. Furthermore, crystallisation, thermal stability and storage modulus were improved for blends with various compatibilisers compared to the neat combinations.

The existence of ABS droplets in PBT noticeably improved the notched impact toughness. The inclusion of carbon nanotubes into the PBT/ABS blend enhanced tensile, flexural and notched impact resistance.
