摘　　要：探讨等离子体改性和织物组织对UHMWPE增强复合板材断裂韧性的协同作用。对平纹、二上二下斜纹和五枚三飞纬面缎纹组织的UHMWPE织物进行了表面等离子体改性处理,以改性前后的织物为增强体,制备了UHMWPE乙烯基酯树脂复合板材,并对复合板材进行了Ⅰ型和Ⅱ型层间断裂韧性测试。结果表明:未改性复合材料的层间及界面性能受织物交织区域影响较大,平纹结构复合板材层间性能优于其他两种组织结构。氧等离子体处理后对织物长浮线区域界面改性效果显著,为斜纹和缎纹结构提供更多纤维桥联和纤维抽拔作用来消耗抵抗分层时的断裂能。Synergistic effect of plasma and fabric weave on fracture toughness of UHMWPE reinforced composite sheet was discussed.Plain weave,two-up-two-down twill and five-heddle satin weave UHMWPE fabrics were treated by plasma on the surface.UHMWPE vinyl ester composite sheets were prepared by fabric before and after treatment.Ⅰmodel andⅡmodel interlamination fracture toughness test were done on the composite sheet.Test results showed that interlamination and interfacial property of the composite fabric without modification were greatly affected by fabric interwoven area.Interlamination properties of plain weave composite sheet were better than the other two weaves.After plasma treatment,interfacial modification effect of fabric long floating yarn area is obvious.It provides more fiber bridging and fiber drawing function for twill and satin structure to consume breaking energy resisting lamination.
